The invention relates to a manufacturing method of guide rail with T-shaped cross section. The guide rail has a first leg, the first end of which is connected to the longitudinal side of the second leg, and a second leg. The guide rail is roll-formed from a flat metal strip in such a way that the metal strip is bent at 180 DEG in a bending area and the second end of which is connected to the longitudinal side of the second leg. The bending area forms a second end, far away from the second supporting leg, of the first supporting leg; wherein two overlapping regions of the metal strip adjacent to the bending area are aligned in parallel by 180-degree bending in the bending area, the two overlapping regions form a first leg in an overlapping manner, and two regions of the metal strip adjacentto the overlapping regions and away from the bending area are bent by 90 degrees in opposite directions from the longitudinal direction of the overlapping regions, and the two regions of the metal strip form a second leg in an overlapping manner. The two regions are referred to as branch legs and form the second leg. According to the invention, the metal strip is bent in the bending region in such a way that the inner side of the overlapping region is in direct surface contact.
本发明涉及一种具有T形横截面的导轨的制造方法及导轨,该导轨具有第一支腿和第二支腿,其中第一支腿的第一端连接第二支腿的纵向侧,该导轨以如下方式由扁平金属带辊压成型:金属带在弯折区域中弯曲180°,该弯折区域形成第一支腿的远离第二支腿的第二端;金属带的与弯折区域相邻的两个叠合区域通过弯折区域中的180°弯曲而平行对齐,两个叠合区域以叠合形式形成第一支腿,并且金属带的与叠合区域相邻的、远离弯折区域的两个区域,从叠合区域的纵向方位沿相反的方向弯曲90°,两个区域称为分支腿并形成第二支腿。根据本发明,金属带在弯折区域中弯曲成使得叠合区域的内侧直接面接触。
